  This 
  is 
  our 
  most 
  common 
  Craterellus. 
  It 
  is 
  easily 
  recognized 
  by 
  

   its 
  elongated 
  tubular 
  or 
  narrowly 
  trumpet-shaped 
  pileus 
  and 
  its 
  dingy- 
  

   gray 
  or 
  smoky-brown 
  hue. 
  The 
  pileus 
  is 
  thin 
  but 
  rather 
  tough 
  and 
  

   elastic. 
  The 
  hymenium 
  is 
  generally 
  a 
  little 
  paler 
  than 
  the 
  pileus 
  

   and 
  varies 
  in 
  color 
  from 
  cinereous 
  to 
  reddish-brown 
  and 
  dark 
  smoky- 
  

   brown. 
  It 
  sometimes 
  becomes 
  pruinose 
  when 
  dry. 
  The 
  stem 
  is 
  

   short 
  or 
  almost 
  obsolete, 
  the 
  hymenium 
  extending 
  nearly 
  or 
  quite 
  to 
  

   the 
  surface 
  of 
  the 
  ground. 
  The 
  spores 
  are 
  larger 
  than 
  in 
  any 
  of 
  our 
  

   other 
  species. 
  It 
  grows 
  especially 
  on 
  naked 
  soil 
  on 
  shaded 
  banks 
  or 
  

   knolls 
  or 
  in 
  old 
  roads 
  in 
  woods. 
  In 
  shape 
  it 
  corresponds 
  very 
  closely 
  

   to 
  Cantharellus 
  foccosics, 
  but 
  in 
  every 
  other 
  respect 
  it 
  differs 
  decid- 
  

   edly 
  from 
  that 
  species. 
  In 
  color 
  it 
  resembles 
  Cantharellus 
  cinereus, 
  

   from 
  which 
  its 
  more 
  elongated 
  pileus, 
  shorter 
  stem 
  and 
  different 
  

   hymenium 
  at 
  once 
  separate 
  it.

   Peziza

  L., 
  Merulius 
  cornucopioides 
  Pers., 
  Merulius 
  

   purpureus 
  With, 
  and 
  Helvetia 
  cornucopioides

  are 
  ancient 
  

   synonyms. 
  

  

  Craterellus 
  dubius 
  Pk. 
  

   Doubtful 
  Craterellus. 
  

  

  Pileus 
  thin, 
  infundibuliform 
  or 
  subtubiform, 
  subfibrillose, 
  dark- 
  

   brown 
  or 
  lurid-brown, 
  pervious, 
  the 
  margin 
  generally 
  wavy 
  and
